Publication number: 20250099052Abstract: A placement mechanism and a flat panel box are provided. The placement mechanism includes a body with a mounting surface configured to place a flat panel and a limiting assembly on the mounting surface. The limiting assembly includes at least two first limiting blocks at a first end of the body, a second limiting block at a second end of the body, and a locking portion. The at least two first limiting blocks include a flange extending over the mounting surface along a height direction of the body. The at least two first limiting blocks and the second limiting block are configured to limit a length direction and a width direction of the flat panel. The locking portion is located at the second end and has a locking member with a locking position and an unlocking position configured to lock and unlock a height direction of the flat panel.Type: ApplicationFiled: September 20, 2024Publication date: March 27, 2025Inventors: Junxiao Zhang, Bo Shi, Yang Tang, Liyong Qin

Patent number: 12242962Abstract: An optimal rescue orbital elements online decision-making method based on RBFNN for launch vehicles under thrust drop fault includes establishing the flight dynamic equations of launch vehicles in the second-stage ascending phase in the geocentric inertial coordinate system, to construct a series of optimization problems of maximum semi-major axis of circular orbit under the thrust drop fault. The method further includes using the adaptive pseudo-spectrum method to solve the optimization problems of maximum semi-major, and using the maximum and minimum method to normalize the sample data to [?1, 1], using the orthogonal least square method to select the data center of the radial basis function neural network (RBFNN), where the Gaussian function is selected as the radial basis function, and the RBFNN is trained offline to establish a nonlinear mapping relationship from the fault states to the optimal rescue orbital elements.Type: GrantFiled: May 26, 2021Date of Patent: March 4, 2025Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Shujun Tan, Xiao He, Liyong Zhang, Zhigang Wu

Patent number: 12173812Abstract: A guide protrusion arranged on a bonnet body of a diaphragm valve bonnet can guide movement of a diaphragm during opening or resetting. A straight through diaphragm valve includes the diaphragm valve bonnet. A fluid control system includes the straight through diaphragm valve. Connecting a control cavity of the fluid control system to a second external pipeline forms a fluid channel at a bonnet end; connecting a fluid cavity thereof to a first external pipeline forms a fluid channel at a valve body end. By regulating pressures of the fluids in the fluid channel at the bonnet end and the fluid channel in the valve body end, the diaphragm can move in the direction close to the bonnet along the guide protrusion to open the fluid cavity, or the diaphragm can reset in the direction far away from the bonnet along the guide protrusion to seal the fluid cavity.Type: GrantFiled: October 9, 2021Date of Patent: December 24, 2024Assignee: NINGJIN APC INDUSTRIES INCORPORATED COMPANYInventors: Shusheng Cui, Liyong Zhang

Patent number: 11998779Abstract: A main valve for a straightway deluge valve includes a valve body (1), a valve cover (2), a diaphragm (3), a drawing piston (4), a diaphragm pressure plate (5), a drawing link (6), a valve body link (7), a valve plate link (8), a rotatable lip and a mounting hole cover (13). A piston guide is provided at a side part of the valve body (1). The drawing piston (4) is provided slidably in the piston guide along a left-right direction. When the drawing piston (4) slides along the piston guide, the rotatable lip can contact with or separate from the inner sealing end surface. The main valve for drawing the straightway deluge valve, after the valve plate (9) is opened, enables the flow passage to be close to a straightway passage, thereby reducing flow loss.Type: GrantFiled: November 25, 2019Date of Patent: June 4, 2024Assignee: Shandong Meihua Fire Technology Co., Ltd.Inventors: Shusheng Cui, Liyong Zhang, Hongchang Liu

Patent number: 8750664Abstract: This invention discloses a bend insensitive single mode fiber, which is composed by a bare glass fiber with a round cross section and two resin protective layers with circular cross sections surrounding the outer of the bare glass fiber. It is characterized in that the bare glass fiber is composed by a core layer with a round cross section and two claddings with circular cross sections. The refractive index of the core layer is higher than the index of the two claddings and the refractive index difference between the core layer and the first cladding is larger than the difference between the first and second claddings. The second cladding is made of pure SiO2. The refractive index profile of the core layer follows a power function, and the refractive index profile of the two claddings follow a ladder-type distribution. The loss of the invented fiber is insensitive to the bending of the fiber, which meets the requirements of ITU.T G.657.A and G.657.B standards, respectively.Type: GrantFiled: July 3, 2009Date of Patent: June 10, 2014Assignee: Futong Group Co., Ltd.Inventors: Liyong Zhang, Weimin Lu, Haigang Wu, Qunxing Li, Xiaopeng Huang
